--------------------------------
Hi, [~zhuqi].
Multi-thread asynchronous scheduling only means support scheduling in multiple
threads, scheduling approaches can be classified as node-based and
request-based, currently fair scheduler only support node-based and capacity
scheduler can support both, global scheduler is request-based and aims for
enhance scheduling performance with considering complex resource placement
requirements.
I think your purpose is to support global scheduler including multi-thread
asynchronous scheduling, multi-nodes lookup mechanism, placement constraints
etc for fair scheduler, Right?
> Add multi-thread asynchronous scheduling to fair scheduler

> Key: YARN-9472
> URL: https://issues.apache.org/jira/browse/YARN-9472
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: fairscheduler, resourcemanager
> Reporter: zhuqi
> Priority: Major
>
> Now the capacity scheduler has multi-thread asynchronous scheduling, i think
> the fair scheduler also need to support it.
